[en] The availability and use of real-time environmental data greatly enhances emergency response and spill monitoring in coastal and near shore environments. The data would include surface currents, wind speed, wind direction, and temperature. Model predictions (fate and transport) or forensics can also be included. In order to achieve an integrated system suitable for application in spill or emergency response situations, a link is required because this information exists on many different computing platforms. When real-time measurements are needed to monitor a spill, the use of a wide array of sensors and ship-based post-processing methods help reduce the latency in data transfer between field sampling stations and the Incident Command Centre. The common thread linking all these modules is the Transmission Control Protocol/Internet Protocol (TCP/IP), and the result is an integrated distributed computing system (DCS). The in-situ sensors are linked to an onboard computer through the use of a ship-based local area network (LAN) using a submersible device server. The onboard computer serves as both the data post-processor and communications server. It links the field sampling station with other modules, and is responsible for transferring data to the Incident Command Centre. This link is facilitated by a wide area network (WAN) based on wireless broadband communications facilities. This paper described the implementation of the DCS. The test results for the communications link and system readiness were also included. 6 refs., 2 tabs., 3 figs
